Estimation of postmortem intervals by using terminal deoxynucleotidyl transferase / 法医学杂志

OBJECTIVE@#To investigate the relationship between DNA degradeation and postmortem interval.@*METHODS@#dUTP was transferred to 3'terminal of DNA by using terminal deoxynucleotidyl transferase (TDT), then the reminders of dUTP after experimental reaction, as indicator of quantity of DNA degradation, were detected.@*RESULTS@#The reminders of dUTP were decreasing along with the postmortem interval.@*CONCLUSION@#Postmortem DNA degradation may be used in postmortem interval judgment.
